Looking very purposeful there in the dappled sunlight. I finally relented and bought a motocross jersey and some under armour, no way could I survive next week's temperatures in my normal textile jacket.
I wear the Acerbis X-Air comp suit with a jersey, and then an old perforated AlpineStars textile jacket on top. Feel a bit naked on the road in just a jersey, mind.
Even this has MOT, since I (occasionally) use it on green lanes.
Definitely getting a bit warm for it though.
